numerous levels based on corporate divisions

That's a good one. I touched on that just a bit in the past but in a spotlight session it could well be expanded.

My basic advice, in a nutshell - information architecture is for visitors, not for in-house ease of use. Large corporates are notorious for having trouble using the web, and this is a bedrock factor.

There is a lot more I could say on this particular facet - and maybe even start some more fights during Q&A ;)
